Variable Frequency Drive

Details :

The Variable Frequency Drives is suitable for any general-purpose application that involves a AC motor, has full of operation functions. Built-in variable digital/analog input functions to suit a wide array of needs. Easy to install and convenient to humanity operating features

New Technology Super Low Noise
Improve soft / hard ware. optimum waveform. The motor as quiet as running with commercial power.

Expansion Of Frequency Range
The range of variable frequency has been greatly extended from 0.5HZ-2000HZ. and S curve for smooth ACC/DEC. performance.

Upgrading V/F Characteristic
Provide constant torque curve (F1) reduce torque curve (F2) and (F3) for FAN/PUMP drive. adjustable saving energy operation and wide basic voltage setting from 30HZ-2000HZ. Double V/F curve performance.

Enhanced I/O Function
Built-in variable digital/analog input functions to suit a wide array of needs. Easy to install. Convenient humanity operating features.

Compact structure
Compact size design make installation easier, it solves space-limited problem.

Extended braking resistor available (braking unit built-in)
All series with extended braking resistor terminals. It makes machine more reliable in high frequency switching RUN/STOP or High speed/Low speed situation.

Cycle timing function
Some models are with cycle timing function for special purpose option. Not only cost down but also using friendly for Timer model replacing general purpose inverter with PLC.
